The PDF file contains a critical heuristic indicating it links to known malicious redirector infrastructure. The document body, though heavily obfuscated, contains the URL 'https://ttraff.ru/pify?keyword=bleach+brave+souls+apk+9.+0.+4', which is also flagged as malicious. This suggests the document's primary purpose is to redirect users to a harmful site, likely for phishing or malware delivery. The presence of numerous other PDF links, many hosted on Shopify, further supports the SEO link farm heuristic, indicating an attempt to game search engine results for malicious purposes.
Heuristics 3
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://ttraff.ru/pify?keyword=bleach+brave+souls+apk+9.+0.+4
